    The vagus nerve (/ ˈ v eɪ. ɡ ə s /), also known as the tenth cranial nerve, cranial nerve X, or simply CN X, is a cranial nerve that carries sensory and motor fibers. It creates a pathway that interfaces with the parasympathetic control of the heart, lungs, and digestive tract. [1]

  3. Vagal tone - Wikipedia

    en.wikipedia.org/wiki/Vagal_tone

    Baseline vagal tone can be used either as a potential predictor of behavior or as a signal of mental health (particularly emotion regulation, anxiety, and internalizing and externalizing disorders). [28] [29] The polyvagal theory by Porges is an influential model of how the vagal pathways respond to novelty and to stressful external stimuli.

    Cranial nerves are the nerves that emerge directly from the brain (including the brainstem), of which there are conventionally considered twelve pairs.Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head and neck, including the special senses of vision, taste, smell, and hearing.

    The vagus nerve. Polyvagal theory (PVT) is a collection of proposed evolutionary, neuroscientific, and psychological constructs pertaining to the role of the vagus nerve in emotion regulation, social connection and fear response. The theory was introduced in 1994 by Stephen Porges. [1]

  8. Central nervous system - Wikipedia

    en.wikipedia.org/wiki/Central_nervous_system

    The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain, spinal cord and retina.The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric and triploblastic animals—that is, all multicellular animals except sponges and diploblasts.

    en.wikipedia.org/wiki/Solitary_nucleus

    The solitary nucleus receives general visceral and special visceral inputs from the facial nerve (CN VII), glossopharyngeal nerve (CN IX) and vagus nerve (CN X); it receives and relays stimuli related to taste and visceral sensation. It sends outputs to various parts of the brain, such as the hypothalamus, thalamus, and reticular formation ...
